Solid State H.F Weld Machine

Power: 300kw

Frequency:400KHZ

Application: Steel Pipe Thickness 2-4mm

solid state H.F welder is specially designed for straight seam welding. It adopts high power components of US IR IRFP460 MOSFET and Germany IXYS Company DSEI60-06A rapid recovery diode. The high power capacitor C and inductor coil L compose current-mode parallel upper-voltage resonance circuit, which doesn’t need output transformer. Thus, it not only improves the efficiency, but also increases the reliability of the welder.

Features:

1. Simple circuit and flexible installation

2. Complete protection and easy maintenance

3. Small harmonic interference, no pollution to the power grid

4. High efficiency, power saving and less cooling water

5. Less welding spatter, good welding quality

The inverter part is made up by MOSFET single phase inverter unit in parallel type. Each unit has self-diagnostic ability. All the design is to ensure easy installation and maintenance.

Automatic load matching system ensures the most efficiency and lowest mill cost.

The Control unit installed with LCD, power and motor speed adjust potention meter. Indicate the output current and voltage of the DC power unit. If necessary, it can indicate armature voltage and current of the DC speed adjusting unit. The pipe line can be completely controlled by the central control unit.

The input rectifier part to ensure stable power supply and insulate the power grid.

The Water-water Heat Exchanger high efficiency of the radiation, use the seal circulation, outer water cools down the inner water, no scaling.

Power Grid Requirement:

Power grid voltage should be sine wave, harmonics distortion: ≤5%.

Imbalance degree between 3-phase voltage: ＜±5%.

Power grid input voltage is line voltage AC 400~410V, continuous fluctuation range: ≤±10%

Power net frequency variation: ≤±2% (i.e. between 49 ~ 51Hz).
